Deprecations and Removals

• #&#8203;116 <https://github.com/pytest-dev/pluggy/issues/116>_: Remove deprecated implprefix support.
  Decorate hook implementations using an instance of HookimplMarker instead.
  The deprecation was announced in release 0.7.0.

• #&#8203;120 <https://github.com/pytest-dev/pluggy/issues/120>_: Remove the deprecated proc argument to call_historic.
  Use result_callback instead, which has the same behavior.
  The deprecation was announced in release 0.7.0.

• #&#8203;265 <https://github.com/pytest-dev/pluggy/issues/265>_: Remove the _Result.result property. Use _Result.get_result() instead.
  Note that unlike result, get_result() raises the exception if the hook raised.
  The deprecation was announced in release 0.6.0.

• #&#8203;267 <https://github.com/pytest-dev/pluggy/issues/267>_: Remove official support for Python 3.4.

• #&#8203;272 <https://github.com/pytest-dev/pluggy/issues/272>_: Dropped support for Python 2.
  Continue to use pluggy 0.13.x for Python 2 support.

• #&#8203;308 <https://github.com/pytest-dev/pluggy/issues/308>_: Remove official support for Python 3.5.

• #&#8203;313 <https://github.com/pytest-dev/pluggy/issues/313>_: The internal pluggy.callers, pluggy.manager and pluggy.hooks are now explicitly marked private by a _ prefix (e.g. pluggy._callers).
  Only API exported by the top-level pluggy module is considered public.

• #&#8203;59 <https://github.com/pytest-dev/pluggy/issues/59>_: Remove legacy __multicall__ recursive hook calling system.
  The deprecation was announced in release 0.5.0.

Features

• #&#8203;282 <https://github.com/pytest-dev/pluggy/issues/282>_: When registering a hookimpl which is declared as hookwrapper=True but whose
  function is not a generator function, a PluggyValidationError exception is
  now raised.

  Previously this problem would cause an error only later, when calling the hook.

  In the unlikely case that you have a hookwrapper that returns a generator
  instead of yielding directly, for example:

  .. code-block:: python

  def my_hook_real_implementation(arg):
      print("before")
      yield
      print("after")
  
  @​hookimpl(hookwrapper=True)
  def my_hook(arg):
      return my_hook_implementation(arg)
  

  change it to use yield from instead:

  .. code-block:: python

  @​hookimpl(hookwrapper=True)
  def my_hook(arg):
      yield from my_hook_implementation(arg)
  

• #&#8203;309 <https://github.com/pytest-dev/pluggy/issues/309>_: Add official support for Python 3.9.
